@tb100: ...when I'm riding my bike, I stick it in my sock. I haven't checked for exact count vs cycles of peddling, but at least it is showing lots of activity now.

I'd be really interested to hear how accurate it is if you say peddle a couple of hundred cycles and then compare the "before" and "after" count on the FitBit -- it woudl be great if you coupel perform this test and then post the result here.

I have a FitBit One, which I like. I noticed that it doesn't measure too many 'steps' when I'm riding a bike. I'm not really looking for much accuracy--just some indication that I've been busy to keep me motivated and moving.

So when I'm riding my bike, I stick it in my sock. I haven't checked for exact count vs cycles of peddling, but at least it is showing lots of activity now.
